First it would be cool if there was tin and copper witch can be combined to make Bronze as an intermediate step from rock to iron. It would also be nice to have an alternative, but not extremly easy, way to get Gunpowder.(Maybe with addition of Mortor & Pestel) One more Idea is to add an bigger workbench, with a 4x4 grid, called a workshop(or sunthin) to make more complicated object. The last suggestion ,I promise, a chemistry kit for potions.
Okay I lied, When you hold a torch it should emit light.
Here are some craft Ideas.
 = Gun
  
 = Mortor & Pestel
= WIN box (Yes, Notch himself has to be inside the box)
= Map (Shows you, all the areas you have explored,and your spawn)
  = Mailbox (send and receive mail among friends)
  = Sailboat
  
  
 = Seat ,When two or more are placed next to each other the make couches, and can be dyed
= Boat = Redstone = Button = Cloth
Thank you for reading the dribble of a fan. Just my suggestions on new things
